If you are a diver, Brockville means two things to you: current and shipwrecks, with the latter making the former worthwhile. Shore dives are virtually non-existent but dive boats are plentiful. Due to the current there is no thermocline – the stratification of layers of water that have dramatically different temperatures. Water temp in the height of summer can rival the Caribbean (I didn’t believe it the first time I heard that either, so don’t worry). Wrecks range in depth from 40’ to over 200’, with the most famous deep wreck being the 650’-long freighter Jodrey which about as amazing as a dive can get. Diving here is generally more advanced than Kingston due to the current.
